Let's divide 3738866 by 403
Our goal is to divide 3738866 by 403.

On to step 1:
When dividing 3 by 403, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 403

Step 2:
37 divided by 403 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 403

Advancing to step 3:
The number 403 fits into 373 0 times, leaving a remainder of 373.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 373 to get 373.
Fetch the next digit (8) from the dividend, attach it to 373 and continue: 3738 / 403

Going ahead to step 4:
If we divide 3738 by 403, we get 9 and a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3627 from 3738, we get 111.
Grab the next digit (8) from the dividend, add it to 111, then carry on: 1118 / 403

Moving on to step 5:
1118 divided by 403 is 2 with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we subtract 806 from 1118, we get 312.
Include the next digit (6) from the dividend after 312, then repeat: 3126 / 403

Advancing to step 6:
3126 divided by 403 is 7 with a remainder of 305.
Put 7 as the next digit of the answer. 
Result so far: 927.0
Deduct 2821 from 3126 and we're left with 305.
Bring next digit (6) of the dividend behind the 305 and repeat the process: 3056 / 403

Let's proceed to step 7:
The number 403 fits into 3056 7 times, leaving a remainder of 235.
Use 7 as the next digit of our solution. 
Result so far: 9277.0
If we subtract 2821 from 3056, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 8:
When dividing 2350 by 403, we get 5 with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 9277.5
Deduct 2015 from 2350 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
When dividing 3350 by 403, we get 8 with a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 9277.58
If we subtract 3224 from 3350, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 10:
403 goes into 1260 3 times with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 9277.583
If we subtract 1209 from 1260, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 11:
510 divided by 403 is 1 with a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 9277.5831
If we take 403 away from 510, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 12:
If we divide 1070 by 403, we get 2 and a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 9277.58312
If we take 806 away from 1070, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 13:
When dividing 2640 by 403, we get 6 with a remainder of 222.
The next digit of our result is 6. 
Result so far: 9277.583126
The remainder is 222 after subtracting 2418 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 14:
When dividing 2220 by 403, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 9277.5831265
Subtract 2015 from 2220 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 15:
If we divide 2050 by 403, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 9277.58312655
Deduct 2015 from 2050 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 9277.58312655 with a remainder of 3.5e-08.
